Exactly six months ago, Eric Schmidt made a remark that in the near future, developers might want to focus on Android first, instead of iOS. While developers haven't moved to Android-first, iOS-later en masse, there's no denying that we're seeing more and more former iOS exclusives move towards Android.

I don't know how many devs would go Android first. I know that when it comes up to try to do something on mobile, I only do Android (and mostly ndk at that). Why? It's good (from a dev point of view - well, at least my dev point of view ), mixing native and java (latter mostly for the ui) is relatively easy (I mean c++ through jni), it's affordable (good emulator, affordable devices to test on, no developer fees). Of course, there could be a chance I would change my mind if I were to develop mobile apps for a living, which I don't, since in that case my choice would be strictly the given OS's market share on the specific market I'd target.
